I suppose if you don’t know cursive, you can’t read it and that would put a damper on your ability to comprehend it if you can’t even read it.
And fine motor skills
If you write legibly, it might. Cant comprehend if I can’t read it, and I can’t read it 90% of the time because whoever wrote it has crappy penmanship since they just wrote big flowing loops or tiny little scribbles instead of words that can be read by human eyes.
